A good quantity, and quality, of sleep is crucial for well-being. Evidence strongly indicates that poor sleep quality and quantity is causally involved in the development of dementia; therefore, techniques which can improve sleep in older adults are very likely to prevent or slow down the disease process in dementia. This project aims to manipulate a specific aspect of sleep in healthy older adults. This: 1) has the potential to prevent the pre-dementia stage of mild cognitive impairment in healthy older adults, and 2) has a direct clinical application to dementia. The overall aim of this project is to investigate if a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can enhance specific brain activity patterns during overnight sleep in healthy older adults. These brain activity patterns during sleep (called 'sleep spindles') are mechanistically linked to both the physiological restorative and the cognitive function of sleep. Sleep spindles can only be assessed by measuring overnight brain activity during sleep. Sleep spindles are very strongly associated with attention, and memory performance, which are severely affected by dementia. A decrease in sleep spindles is associated with cognitive decline, and predict dementia development. Therefore, enhancing sleep spindle activity in sleep is likely to boost cognition. Whilst previous research studies have demonstrated that in a sleep laboratory environment, tDCS can manipulate sleep spindles when individuals are in a specific brain state in a nap situation, we are specifically interested in testing tDCS in a home environment. This is because the use of tDCS in a home environment has have a number of advantages over sleep laboratory studies. Specifically, by conducting this study in a home environment, this will maximise the inclusivity of studies involving older adults, and DLB patients, since they will not be required to travel to a sleep laboratory to participate in studies. The aim of this proof-of-principle study is to investigate if tDCS can manipulate sleep spindles in healthy older adults. It is expected that relative to a placebo stimulation, active stimulation (which exerts an effect upon the brain) will increase sleep spindle activity in healthy older adults.
This is an early phase study to assess the safety and tolerability of ONO-4685 in patients with psoriasis. In addition, the study will assess how the drug is distributed and eliminated by the body (pharmacokinetics) and how the drug affects the body (pharmacodynamics). This will be done by measuring the amount of drug in the blood and measuring other markers in the body that might have been affected by ONO-4685. The study will also look at preliminary information on whether ONO-4685 might be effective in treating psoriasis. The study will be split into three parts. Part A will assess a single dose of ONO-4685 in small groups of patients, each group planned to receive a higher dose than the last group. In Part B and C, patients will receive multiple doses of ONO-4685 over a period of 4 weeks.
Many people do not manage to do the recommended amount of physical activity for improving general health and wellbeing, and a common reason for this is lack of time. Sprint interval training (SIT) has been suggested to be a time-efficient alternative to current exercise recommendations, but most SIT protocols are not actually as time-efficient as claimed. However, it has previously been shown that the training time commitment of common SIT protocols can be substantially reduced while remaining effective at improving key health markers such as aerobic fitness, insulin function and blood pressure. For example, the reduced-exertion high-intensity interval training (REHIT) protocol consists of two 20-second 'all-out' cycle sprints within a 10-minute low-intensity exercise session. There is some evidence that REHIT is just as effective at improving aerobic fitness with 2 exercise sessions per week compared to 3 or 4 sessions. However, it remains unknown if improvements in aerobic fitness are reduced if just a single REHIT session is performed each week. Therefore, the aim of the present study is to compare improvements in aerobic fitness levels between a control group (no training intervention), a group performing a single REHIT session per week, and a group performing 2 REHIT sessions per week.
This Phase 1a/1b study will evaluate the safety, tolerability and the pharmacokinetics/ pharmacodynamics (PK/ PD) of KT-413 in patients with R/R NHL. The Phase 1a stage of the study will explore escalating doses of single-agent KT-413. The Phase 1b stage will be split into 2 expansion cohorts to further characterize the safety, tolerability and the pharmacokinetics/ pharmacodynamics (PK/ PD) of KT-413 in MYD88 mutant and MYD88 wild-type R/R DLBCL.

There are two parts to the study: - Part A - evaluation of serial tumour biopsies - Part B - evaluation of circulating biomarkers and other biospecimens
Near infrared spectroscpy is a validated method of evaluating cerebral blood flow. The aim in this pilot study to explore its use in children with moyamoya disease.
The purpose of the registry is to evaluate the peri-operative and short- term outcomes of intercostal nerves cryoablation for post-operative pain control after open thoracic and thoracoabdominal aortic aneurysms repair. The cryoablation procedure is one of the opportunities for pain control after thoracotomy. So, it is routinely performed in major several centers in aortic surgery around the world as a part of the TAA and TAAA procedure. The Registry will include approximately 200 patients treated from January 2022 to January 2024 for thoracic or thoracoabdominal aortic aneurysm by means of open surgery and in whom intraoperative intercostal nerves cryoablation will be performed; to reach 200 patients, the enrolments can be extended until January 2027.
Purpose: To investigate the impact of exercise load on resistance exercise-induced muscle damage in untrained males and females. Rationale: Unaccustomed resistance exercise can cause muscle damage, presenting as muscle soreness and reduced muscle function - such as loss of strength, power, and flexibility - for several days after the exercise bout. Therefore, individuals may require longer recovery periods before performing another exercise bout, and their performance may be impaired. Further, muscle soreness may reduce exercise compliance, particularly in novice individuals. Over time, this may compromise the gains in muscle mass and strength achieved through exercise training. Therefore, strategies to reduce the severity of exercise-induced muscle damage and/or to enhance post-exercise recovery processes are advantageous for exercising individuals. One such strategy is to perform resistance exercise with lighter loads, i.e. <70% one repetition maximum (1RM). Low-load resistance training has shown to induce comparable gains in muscle mass and strength to high-load (≥70% 1RM), while being perceptively less exerting. Low-load resistance exercise may place less mechanical stress on muscle fibres and accordingly, its impact on muscle damage has been investigated. While several studies have reported less severe muscle damage, muscle soreness, and functional impairments with low-load resistance exercise compared to high-load, others have found no differences. Further, there is a lack of studies conducted solely in females or comparing between sexes. It has been suggested that males and females respond differently to muscle damage, and therefore, this research aims to provide a sex comparison in the muscle damage response to an acute bout of resistance exercise performed with low or high loads. Therefore, 40 healthy, young (18-35 years) adults (20 males, 20 females) will be recruited to participate in this randomised controlled trial. Maximal leg strength and body composition (by dual-energy X-ray absorptiometry; DXA) will be conducted at baseline. In females, all primary outcome measures will be obtained during the late follicular phase of the menstrual cycle. Participants will then be randomised to a low-load (30% 1RM) or high-load (80% 1RM) exercise condition. Three weeks later, participants will complete a resistance exercise session at their allocated intensity on leg extension and leg curl machines to induce muscle damage. Various measures of muscle damage (blood biomarkers, muscle soreness, flexibility, and swelling) will be obtained before, immediately after, and 24, 48, 72, and 168 h after the exercise protocol. The maximal strength test will be repeated 72 and 168 h after the exercise. Participants' habitual activity and dietary intake will be monitored and controlled throughout the study period. Expected outcome: It is expected that the resistance exercise protocol will induce muscle damage, which will be less severe in the low-load exercise condition. It cannot be ascertained whether males and females will have the same responses to the exercise.
The purpose of the study is to determine the efficacy of pegcetacoplan administration compared to placebo in increasing hemoglobin (Hgb) level from baseline and avoiding transfusion in participants with primary cold agglutinin disease (CAD).
SmokeFree is a theory-driven and evidence-based stop smoking mobile application. Based on NICE guidance and best practice for smoking cessation, the application employs over 30 behaviour change techniques used in NHS Stop Smoking Services. It has been downloaded over 4 million times and has an average user rating of 4.7 out of 5, from over 120,000 ratings. Whilst user feedback has been highly positive, there is a need for further objective studies to demonstrate its efficacy. This is a prospective, observational, two arm feasibility study, which aims to evaluate the efficacy, attrition rate and user experience of the SmokeFree App. Inpatients in the Acute Medical Unit and ambulatory emergency care unit at Chelsea and Westminster Hospital who are current smokers will be offered to participate in the study, in addition to all other smoking cessation interventions, which will also be offered to them. Care will be taken to ensure that all available options of smoking cessation support are offered in addition to the SmokeFree application. Subjects agreeing to participate will be given access to the application for a period of 12 weeks, with a target quit date no later than week 8 of use of the application. At the end of 12 weeks they will be offered a follow up appointment in a purposely designed clinic, where their CO level will be measured, as well as being invited to complete feedback questionnaires on their experience. The primary end point of the study will be the quit rate for a period of minimum of 4 weeks by the completion of the 12 week trial. This will be confirmed with exhaled carbon monoxide testing. Secondary endpoints include user experience, engagement with the mobile application and attrition rate.
